Discussion of group technology

The auxiliary hole outside the center line (the third code is 2); made of gray cast iron (the fourth digit code of 6) of the disk parts. It can be seen encoded in wonderful shape the role of several generations of 0.) Using a four code. Institutions will be able to draw a part of the shape, size and materials. China's machinery industry sector in the implementation of machining coding system is JLBM-1 system. The system is a decimal code of the hybrid structure fifteen classification and coding system, which increased the horizontal classification link, and the increase in the number of vertical limited. 2GT the economic benefits of technological development with the increasingly diverse needs of the community, identified a number of varieties of small batch production dominant position. According to statistics, China's manufacturing industry is very large proportion of small and medium volume production up to 80% or more, in order to develop export-oriented economy, in the fierce international competition in the market gain a firm footing, we must develop more and more new products, while the bulk is smaller and smaller. This requires that the factory has strong adaptability. Implementation of group technology available to a wide range of economic benefits. Group technology to deal with a group of similar parts group in the production in a variety of problems, which can save a lot when asked, raising labor productivity. Used as (continued on page 1 Cool

l8 Machinery Development 1 1998 users are very satisfied. (3) high-speed steel battery shell forming punch Yunan a hardware factory in Guangdong Province deposition processing of high speed steel battery shell forming punch. The red bar coated with TiN (TiN hardness of up to 2500HV). High surface hardness. Low coefficient of friction. Reduce the strain phenomenon. Improve accuracy. And service life increased by 4 times. 7 Conclusion (1) increasing the vacuum chamber of the heat shield. Improve the workpiece temperature zone, to avoid differences due to temperature stress caused by the film; improved graphite crucible. E-Cambodian fighting against the edge of the crucible to affect the coating quality; to improve the workpiece frame, so that the workpiece holder in the deposition process running smoothly. (2) of the HCD ion plating process and the parameters of TiN on the TiN coated end table, hardness and the color can be obtained with high hardness, combined with the TjN strong coating. (3) After deposition of the high-speed copper lTjN cutter, drill, punch and fine cross high-speed steel battery shell punch, with its life can be improved 3-5 times. Has great application value.

A similar process to eliminate the unnecessary diversity of parts,ugg stiefel, processing, management of family units selected process plan,ugg boots ireland, so that the workpiece quality is stable and reliable. Preparation of production workers in the production unit or the assembly line, process specialization increased. Is to enhance the proficiency of workers labor in the production unit into a group of workers from the head to the quality of overall responsibility for the part to enhance the production of sense of responsibility; with a high degree of automation equipment. . Reduce the human factors impact on the processing quality, the scrap rate. With classification and coding system, new products drawing most of the original components can still be used. Reduce design effort. Thus shortening the design cycle. Improve the design of new and old products, inheritance, design and manufacturing process will inevitably bring about the inheritance. Thus greatly simplifying the technical preparation of new products. Technical preparations to shorten the production cycle. After the implementation of group technology. Changes in the original variety, small batch production enterprises messy, scattered and backward Rotary conditions. Reduce the design, technology and other unnecessary repetition and diversify the management difficulties. Advanced forms of production organization streamline the production management. Part of the product coded for the use of computer management of production basis. Groups of parts in the production unit or pipeline processing. Parts do not like the traditional mode of production,ghd deutschland, as approved by the order for inter-process flows. In principle, piece by piece or several pieces can be passed into. This reduces the time in question and storage products amount, thus a corresponding reduction in the cost of spare parts inventory. As groups of parts enclosed in the corresponding production unit or assembly line. Therefore greatly reducing the auxiliary send route. Reduce the workload of parts and auxiliary transport, to achieve physical and chemical material flow units. So get implemented into the economic benefits of satin technology are manifold.
